DEVICE FOR SEALING FRUlTnJ/HS.

SPECIFICATION forming part of Letters Patent No. 660,092, dated October 23, 1900.

Application filed July 15,1899. Serial No. 723,971- (No model.)

To fr/Z whom it may con/cern,.-

Be it known that I, WILLIE BURCH, a citizen ofthe United States, residing at Lowell, in the county of Kent and State of Michigan, have invented a new and useful Device for Sealing Fruit-Jars, of which the following is a specification.

My invention relates to jar and bottle cloeures, and the object thereof is to provide a device of the character described which is adapted to herin etically seal any vessel-such as a jar, bottle, or canbut more particularly milk or preserve jars and glass bottles.

lVith this object in view myinvention consists of a vessel, preferably of glass, on either side of which is located a segmental projection having a groove therein, the top edge of the vessel being flat to receive a packing-ring, and a flanged cap on the packing-ring, a screw actuated locking-plate above the cap having two oppositelyldisposed engaging bails designed to operatively connect with the segmental projections on the side of the vessel.

My invention further consists in certain details of construction, all of which will be Vfully described in the following description, recited in the claims, and illustrated in the drawings, in which Figure 1 is a perspective View of aglass jar constructed in accordance with my invention. Fig. 2 is a verticallongitudinal section therethrough. Fig. 3 is a'perspective View of a bottle, showing the cap of a modified construction; and Fig. a is a section through the SitlllG.

Referring now to the drawings by reference-numerals, 5 indicates the jar or bottle, preferably made of glass and provided with the usual restricted neck, the top edge of which it is designed to cast or mold perfectly square; but in the process of manufacture the surface of this edge is sometimes unequal, but, as will later appear, I have provided for any inequality which may occur.

At a suitable point below the top of the jar or bottleand diametrically opposite are two semicircular or segmental ears 6, provided with the peripheral grooves 7.

8 indicates a packing ring or disk of suitable resilientniaterial, such as rubber orcork, positioned upon the top edge of the neck and held thereon by the cap 9. In a jar construction this cap will be slightly different than when used on a bottle. For instance, the jar will be provided with a cap having an out* wardly-projecting flange 10, designed to rest upon the top of the packing-ring, and the downwardly-extending flange 1l, designed to extend into the neck of the jar, and thus form a right-angular groove 12, into which the i'nner edge of the packing-ring will [it snugly and when the cap is pressed rmly down an air-tight joint will be formed. In a bottle the cap 9 will be provided with the downwardly'- projecting ange 10, which will fit over the packing-disk and neck, as shown in Fig. 4. On top of this jar-cap is an annular groove 13,in which the edges of a locking-plate 14 will normally rest.

15 represents radially-extending eye-early ing lugs or projections on the top of the locking-plate, which may be cast thereon or struck from the metal with a suitable die if the same is made of sheet metal, and said lugs or projections are arranged in oppositely-disposed pairs. Hingedly connected to each pair of the lugs or projections l5 is a baillike loop 16, and said loops engage the grooves of the ears (i. Into the central threaded perforation of the locking-plate is then inserted a screw 1 7, which will have any kind of a suitable head, so that when the same is turned the cap will be forced down on the packing-ring as tightly as desired, and any inequality of the upper edge of the jar will be taken up by the packingring heretofore referred to.

"While I have described the very best means at mycoinmand for accomplishing the desired result, I do not abandon the right to make such slight changes and alterations as would properly come within the scope of my invention withontdeparting from the spirit thereof.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is

l. In a closure of the class described, the combination with a vessel provided at its sides with oppositely arranged ears, of a' cover, a locking-plate arranged above said cover, said plate being provided with radially-extending lugs or projections arranged in oppositely-disposed pairs, a locking-bail hingedly connected to each pair of said lugs or projections and adapted to engage the ears IOO 1o in the groove thereof, locking-baile carried by said plate and adapted no engage the ears of the jar, and a screw aise carried by the locking-plate, and bearing against the Cover for binding the 1ockingbai1s in engagement With said ears.

WILLIE BURCH.
